## Water wells in Riley County

**3,583** WWC-5 records — 1.1% of the Kansas register. The median well here is **50 feet** deep, against 60 feet statewide.

### How deep people drill in Riley County

This is what a buyer or a builder actually wants, and the Survey does not publish it as a figure you can look up. The numbers below are medians over the records where a figure was reported — a mean would be carried away by a few deep irrigation wells.

*Medians, on the records where the driller reported a figure — never a mean, which a handful of deep irrigation wells would carry away*

| Measurement | Median | 90th percentile | Kansas median |
|---|---|---|---|
| Depth | **50 ft** | 180 ft | 60 ft — shallower here (3,578 records, 100 %) |
| Static water level | **24 ft** | 84 ft | 24 ft — the same here (2,899 records, 81 %) |
| Estimated yield | **20 gpm** | 100 gpm | 25 gpm — lower here (1,532 records, 43 %) |

### Wells tied to a water right

**211** records in Riley County carry a DWR
appropriation number — 5.9%, against 11.0% statewide. A
well permit and a water right are separate instruments in Kansas, and the
appropriation number is the thread back to the Division of Water
Resources.

### What stands out in Riley County

The busiest contractor on these records is **Associated Environmental, INC**, named on 596 of them (16.6%), ahead of Haldeman Well Drilling & Pump Service (336) and Strader Drilling Co., INC (335). The oldest record here was completed in **1975** and the most recent in 2026, and the deepest well on file reaches **400 feet** — a domestic well drilled by Associated Environmental, INC in 2003.

### Plugging records — in Riley County

**858** of the 3,583 records in Riley County carry a
plugging report (23.9%), filed on form WWC-5P. The other
**2,725** do not.

That is **not** a list of abandoned wells, and
this site never calls them that. Kansas defines abandonment by
*use* — a well unused for two years — and nothing in this
register tracks use. What the absence of a plugging report does mean is that
the State has never been told the well was sealed. On the
**949** records here completed before 1995, that is
exactly what a buyer checks. [Why it matters and who
pays](/abandoned.md).

### An unplugged well on land in Riley County?

2,725 of the 3,583 records in Riley County have no plugging report on file. If a well on your land is no longer used, Kansas requires it to be plugged and the duty falls on the landowner — with cost-share of up to USD 1,000 per well through the Kansas Department of Agriculture. This site reads the register; it does not drill and it does not plug. Tell us where and we pass the request to licensed Kansas well contractors.

We recommend no contractor and we are nobody's agent. We have no arrangement with any firm today — we are collecting these requests in order to go and find them. [What we do with this](/privacy.md).

### Records in Riley County

*Riley County — « plugging report » reads *yes* where a WWC-5P was filed and a dash where none was, which is NOT a finding that the well is abandoned. A 0 means the driller reported no figure, not a measurement of zero. The legal description is on the record, never on a page.*
